Six other substances were identified as being a part of the Fatty Acids and Derivatives Group at the outset of the third phase of the CMP.

Four of the 6 substances [CAS RNs 68139-89-9, 53980-88-4, 68647-55-2, and Domestic Substances List (DSL) Confidential Accession Number 11556-0] were subsequently determined to be of low concern to both human health and the environment, through other approaches.  Conclusions for CAS RN 68139-89-9 are provided in the Screening Assessment for Substances Identified as Being of Low Concern based on the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances.  Conclusions for CAS RNs 53980-88-4, 68647-55-2, and DSL Confidential Accession Number 11556-0 are provided in the Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.

The remaining 2 substances (CAS RNs 68476-03-9 and 73138-45-1) were placed into another substance group to which they are more appropriately suited on the basis of scientific considerations. Conclusions for these substances are provided in the Screening Assessment for Seven Hydrocarbon-based Substances.
